Yes. Good. Let’s go painfully slow and do it sentence by sentence, very plainly.
Here’s the paragraph again in pieces.
Sentence 1:
“The interest of citizens in one or other form of government is not necessarily shared by their political representatives.”
Translation:
What regular people want is not always what politicians want.
Citizens care about good policy.
Politicians care about their careers.
Sentence 2:
“Local politicians will lose, and central politicians gain, from centralisation, whatever the benefits to their citizens.”
Translation:
If power moves to the center:
- Local politicians lose power.
- National politicians gain power.
And this is true even if centralisation is good for citizens.
So politicians judge it by who gets power, not just by whether it helps people.
Sentence 3:
“Furthermore, if some politicians are potentially mobile, in the sense that they have a significant probability of forming the government under either central or local arrangements, their incentives are perverse.”
Break this down.
“Potentially mobile” =
Some politicians could end up in power under either system (local or central).
So they don’t care which level they rule at — they just want to rule somewhere.
“Incentives are perverse” =
Their motivations don’t line up nicely with what’s good for society.
Why? We’re about to see.
Sentence 4 (the big one):
“They will have an interest in arguing for centralisation only when its impact in reducing accountability outweighs its beneficial impact on internalising spillovers…”
Slow down.
Centralisation does two things:
-
Reduces accountability
→ Harder to remove politicians
→ Good for politicians
-
Fixes spillovers
→ Makes policy more efficient
→ Good for society
The sentence says:
These mobile politicians support centralisation only if the reduction in accountability is more important (to them) than the spillover benefit.
In other words:
They support centralisation when it helps them personally more than it improves policy.
Final part:
“…since under these circumstances the level of effort they have to undertake will be reduced.”
This is the key.
Politicians have to put in effort to:
- Make good policies
- Satisfy voters
- Win elections
If accountability is high → they must work hard.
If accountability drops → they can slack more.
So they support centralisation when it reduces how hard they have to work.
The whole paragraph in idiot language:
Citizens might want the system that produces better policy.
Politicians want the system that:
- Gives them more power
- Makes it harder to fire them
- Lets them work less
So some politicians will only support centralisation if it mainly makes their jobs safer and easier — not just because it improves coordination.
